Class
    Foam::contactAngleModel
 
Description
    Abstract base-class for contact-angle models
    which return the cosine contact angle field.
 
Usage
    Example of the surface tension specification:
    \verbatim
        contactAngle
        {
            type                <contact angle model type>;
            <coefficient name>  <coefficient value>;
            .
            .
            .
        }
    \endverbatim
